ROLLER-HINGE FOR GATES.

SPECIFICATION forming part of Letters Patent No. 339,458, dated April 6, 1886.

Application filed December 30, 1885. Serial No. 187,077. (No model.)

To all whom it may concern.-

Be it known that I, EDDY THOMAS MCKAIG, a citizen of the United States, and a resident of Chicago, in the county of Cool: and State of Illinois, have invented certain new and useful Improvements in Roller-Hinges for Gates; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure l is a side View of a gate provided with my improved rollenhinge. Fig. 2 is a plan view showing the gate opened. Fig. 3 is a vertical sectional view through the rollerbearing pivot. Fig. 4 is a perspective view of the rollerbearing pivot and the eyebolts, showing the rail of the fence in dotted lines as well as the post. Fig. 5 is a perspective view showing the parts composing my improvement separated, and Fig. 6 is a crosssectional view of one of the eyebolts.

Similar letters of reference indicate corresponding parts in all the figures.

My invention has relation to roller-hinges for that class of gates in which the gate-panel has one or more of its rails traveling upon a roller which is journaled within a box having vertical pivots, so that the panel may be rolled to one side until one half of the panel will counterbalance the other half, when the gate may be swung upon the pivot and opened; and it consists in the improved construction and combination of parts of such a hinge, as hereinafter more fully described and claimed.

In the accompanying drawings, the letter A indicates the panel of the gate. Bis the central rail of the panel, which travels upon the roller, and C is the hinge-post.

The roller D, upon which the rail travels, is jonrnaled with the ends of its shaft E in bearings F F, formed in the lower ends of two side pieces, G G. By having lugs or rings around the bearings F F, as shown in Fig. 3, and the hub of the roller secured between them, the outer rim of the roller will not bear against the sides of the hinge, and thus the friction of the roller will be reduced to the least possible amount. Said pieces G G have flanges I. and H at their upper and lower ends, and hollow halfpintlcs J and K at the outer sides of the flanges, so that when the two side pieces are placed together the flanges will form the end pieces for the rollcnframe, and thehalf-pintles,bearing against each other, will form hollow pintles. The bottom flanges, H, have notches at the inner ends of the halfpintles, so that the bore of the pintle will extend directly through the bottom flange or end piece, while one of the top flanges is formed with a semicircular notch, L, at the base of the half-pintle, and the other flange is formed with a semicircular lip, M, which will fit into the notch and close the bottom of the hollow pintle. In this manner snow, water, or dirt which may accumulate within the pintle at the upper end of the frame cannot drop down upon the rail or down upon the roller, while any dirt which may accumulate between the roller and the lower end piece of the frame may drop through the hollow pintle.

The eyebolts N and O are driven into the corner of the hinge-post, standing at angles of forty-five degrees to the sides of the post, and the lower eycbolt is formed with a closed round eye, 1?, at its outer end, while the upper bolt is formed with an eye, Q, open atits outer side, and having perforations 1t R in the branches of the open eye or bifurcated head, through which perforations a split key, S, or bolt may be inserted.

The inner portions of the bolts are triangular in cross-section, and formed with aserrated edge, T, and with alongitudinally grooved or recessed side, U, opposite to the serrated edge, so that in driving the bolt into the post the wood will swell up after the bolt has been driven into it and iill up the groove, preventing it from being withdraw n,together with the serrated edge, while the said grooved side will also serve to allow the wood to expand into the space opened by the bolt, and thus aii'ord it a relief, preventing it from splitting the wood by wcdging it away from the bolt in all directions.

The eyes will hold the halfpintles together, and thus hold the entire frame together, and the lower pintle is first placed in the lower eye, whereupon the upper pintle is slipped into the upper eye and the eye closed by means of the key or pin, when the rail-supporting frame will be securely held and pivoted.

The rail may be placed within the frame resting upon the roller by placing one half of the frame around the rail from each side, and by now hanging the gate with its pintles in the eyebolts the halves of the frame are held together and the gate is supported so that it may roll and swing.

The semicircular tongue at the bottom of the upper half-pintle of one frame-half fitting into the semicircular notch in the flange of the end piece of the other frame-half will serve to hold and guide the two piutle-halves together, preventing t-hem from becoming separated or from roekin g against each other, the upper eye with its open side and key or pin being less secure than the lower eye, and for this reason, as well as for the reason above mentioned of preventthe pivoted roller-frame the gate-panel may be made and finished before placing the frame upon the track-rail, the roller-frame being the last thing to be adjusted in hanging the gate.

By this construction the gate may easily be taken off from the hinge, and may as easily be replaced,andif any portion of the roller-hinge, the roller, any one of the frame-halves, or the eyebolts should be damaged or in any way injured, the said part may be replaced without the necessity of procuring an entire hinge.

Having thus described my invention,I claim and desire to secure by Letters Patent of the United States-- The combination of two recessed halves of a gate-hinge, the lower pintle of which is hollow and the upper pintle closed by means of a projection upon one of the halves fitting within a recess upon the other half, eyebolts for said pintles, and a roller journaled in bearings in said halves, as shown and described.

In testimony thatI claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.

EDDY THOMAS MCKAIG.
